PASTlNG-MACHINE FOR (DOLLARS, 840.

SPEGIFIGATION forming part of Letters Patent No. 676,793, dated June 18,1901-. Application filed September 12, 1899. Serial No. 730,220. (Nomodel.)

To all whom it may concern:

Be it known that I, ALBERT D. FENwIcK, a citizen of the United States,and a resident of Boston, Massachusetts, have invented certain new anduseful Improvements in Pasting-Machines, of which the following is aspecification.

My invention relates to pasting-machines, and is particularly intendedfor use in apply- :0 ing paste to the blanks of collars and endspreparatory to pasting such blanks together and stitching them.Heretofore this work has been done by hand and has been slow and notaltogether satisfactory, as a careless operator might apply too muchpaste or apply it at the Wrong points on the blank.

It is the object of my invention to provide a construction that shallmake it possible both to apply the paste more rapidly than by hand andto do it in a more satisfactory manner.

To this end my invention consists in combining with suitable actuatingmechanism a series of paste-carrying tubes or fingers arranged andadapted to deposit an accuratelyregulated quantity of paste at anydesired points on the blank to be pasted.

Another feature which characterizes my invention consists in providingfor the paste areservoir from which the air may be wholly 3o excluded,so that it cannot mingle with the paste and cause it to sour or spoil.

A third novel characteristic consists in combining with thepaste-applying means novel mechanism for accurately regulating thequantity of paste supplied thereto Within any desired limits.

Still another feature consists in so arranging the paste-applyingfingers and the operating mechanism that the paste may be applied at anydesired points and to different forms and sizes of blanks.

These and other features of my invention will be particularly explainedin the following specification and clearly set forth in the 5 claims.

Referring now to the drawings, in which I have illustrated one of themodes of embodying my invention, Figure 1 is a side elevation of theentire machine. Fig. 2 is an end elevation thereof. Fig. 3 is a planview showing the means for supplying the paste to the ends of thefingers in properly-regulated quantities. Fig. at is a verticalsectional View on the line 4 4 of Fig. 3. Fig. 5 is a centralverticalsection showing the device for filling the paste-tubes, one ofthe tubes being shown immediately below ready to be attached forfilling. Fig. 6 is a plan view of the strainer contained in the fillingdevice.

In the practice of my invention as illustrated in the drawings I providea suitable table a resting upon the framework Z) of the machine, whichserves to support in proper position the blanks to be pasted.

The paste carrying and applying device comprises a tube or reservoir 0,provided at its lower end with a short substantially conical nozzle d,which has an outlet at its apex. The nozzle is detachable fromthe tube.Upon the exterior of the nozzle is secured a ring or guard 6, whoselower edge lies slightly below the plane of the contracted end or pointof the nozzle. A plunger or pistonf, having a suitable packing-disksecured to its bottom,

. fits closely the bore of said tube and is forced downward by means ofa screw threaded plunger-rod g, whose lower end rests loosely in asocket on the upper face of the plunger. The plunger-rod is preventedfrom turning by a spline connection h with the flanged head 2. Aninternally-threaded rotatable hubj, having secured to its topratchet-disk 7r, serves to depress the plunger in the tube. Gibs or pinsZ may be employed to prevent the withdrawal of the hub from the headWithout interfering with its turning. An arm or lever m, loosely mountedto turn on the hub j and provided with a spring-pawl n, serves tointermittently rotate the ratchetdisk 7a and the hub The means foroscillating said pawl-carrying arm to actuate the disk consists of areciprocating rod 0, mounted to slide in suitable brackets and havingprojecting fingers engaging with the forked ends q of the arms m, sothat as the rod slides it moves the arm or about the hub j as an axis.Each forward movement of the pawl carries the disk with it; but on thereturn movement of the pawl the disk is stationary, being held in placeby spring-detents r. The fingers 19 may be secured to the rod 0 by meansof sleeves provided withset-screws, so that they may be properlyadjusted. The slide-rod is held normally pressed to the right throughthe action of the spring 5 and the slotted bellcrank lever 15, which isconnected with the 5 slotted link u by an adjustable stud w. Theslide-rod 0 is moved forward by means of the arm a on the rock-shaft b,which is actuated by a swell on the cam c, said arm a being connected tothe bell-crank lever 25 by means of the chain (1. Motion is imparted tothe drive-shaft e from the power-shaft f by means of the clutch-hub g,the sprocket-chain h, and its two sprocket-wheels, the idlersleeves 22,carrying the pinion i, and the gear j, which meshes with said pinion andis secured to the drive-shaft e. A treadle 70 serves to keep the clutchmember in operative engagement when it is desired to run the machine.The drive-shaft c carries the cam 0, whose function has already beenexplained. It also carries another cam Z, which actuates the rock-shaftm through the medium of the arm n. The rock-shaft m is provided withslotted forked arms 0, which engage with pins 19 on the sliding sleevesg, which sleeves carry. lifting-rods r. These lifting-rods supportcross-heads s, in which are secured the rods t, which thus form acarrier or frame for the paste-carrying tubes, which are adjustablysecured thereon by means of the brackets u,the flanged heads t', and theclamping wings or collars w, the brackets it being held rigidly andadjustably in place on the rods by means of the set-screws a To permitan adjustment of the tubes transversely to the rods 16, the bracket maybe slotted, as shown at b in Figs. 3 and 4. It is sufficient, however,to make the middle tube only adjustable in this way. To accommodate thisadjustment without varying the length of the arm m,that moves theratchet-disk, the sleeve 0 which carries the pin 19, may be adj ustablymounted in a yoke d adjustably secured to the slide-rod 0. As the tubeis moved back in its supporting-bracket the pin -carrying sleeve may bemoved back a corresponding distance, so that it will properly engage theforked end (1 of the arm m.

From the foregoing it will be seen that the mechanism for actuatingtheplungers acts independently of the means for reciprocating the tubes, sothat the extent of movement of either mechanism can be varied withoutatfecting the movement of the other. Moreover, the change of relativeposition of the tubes to each other does not interfere with or vary theaction of the pasteexpelling means, since the expelling mechanism iscapable of adjustment to accommodate any change in position of thetubes.

The operation is as follows: A pile of collar-blanks is laid upon thetable in proper position beneath the paste-applying fingers. Theoperator then depresses the pedal and thus starts the machine. Throughthe medium of the cam Z, the rock-shaft m and its projecting arms, andthe connecting-rods the paste-fingers are alternately raised andlowered. As will be understood, the cam Z and the rock-shaft arms raisethe verticallyreciprocating framework positively; but its descent is dueonly to gravity. In order to prevent jar, as well as to ease the runningof the machine, the rock-shaft may be partly counterbalanced by a weightg. The cam c is so coordinated in its action with reference to the cam Zthat it depresses the arm a, and thereby moves forward the slide-rod 0when the paste-fingers are at the top of their traverse. This forwardmovement of the sliderod swings-the arm m through the arc of a circle,moving the ratchet-disk 76 and the hub j through a corresponding arc.The internal thread of the hub or sleeve j, acting upon the thread ofthe plunger-rod, causes said plunger-rod and the plunger to slightlydescend, and thus to force a small quantity of paste through thecontracted nozzle 01, so that a drop of paste falls from each tube uponthat point of the blank directly under it. The guard 6 projects slightlybeyond the lower end of the nozzle and prevents the tube from descendingfar enough to allow the nozzle to come in direct contact with the blank,thereby making it impossible for the blank to stick to the paste-fingernozzle when the finger rises. As will be understood, the distance whichthe plunger descends at each operation depends upon the extent of theare through which the ratchet-disk is moved by each stroke of-theslide-rod, which in the construction shown is determined by the lengthof stroke of the slide-rod. The length of this stroke is varied byshifting the position of the adjustable stud or connecting-pin 10. Asshown in the drawings, this pin is set to give the maximum stroke, atwhich. point the ratchet may be turned through an arc of, say, sixteeth. By setting said pin at the bottom of the slot in the lever 25 itis obvious that the length of the stroke of the rod will be shortened inthe ratio that the radius of the movement of the pin in its lowerposition bears to the radius of its movement in the highest position. Asthe quantity of paste applied will depend upon the distance that theplunger is depressed on each stroke, it will be seen that the feeding ofthe paste can be absolutely and accurately regulated by shifting the pinto.

I have provided a special device for filling the tubes or reservoirswith paste without allowing the air to mingle with it. One form of thisdevice is shown in Fig. 5 and is somewhat similar in construction to thepaste tubes. It comprises a tube 1, which is screwed into asupporting-head 6, which carries a rotatable hub or sleeve 7, to whichis secured a hand-wheel S by means of gibs 9. This hub is-interiorlythreaded to receive the threaded plunger-rod 5, which has a splinegrooveconnect-ion with the head (i, as shown at 6, which prevents the rotationof the plunger-rod, though permitting-it to move vertically in saidhead. The piston or plunger 4 stares is secured to the end of the rod 5and is provided with a suitable packing-disk to make it fit snugly inthe tube. The device is supported by the brackets 2 and 3, which may beattached to a backboard A or other suitable support. To the lower end ofthe tube is fitted a funnel-shaped cap or nozzle 10, whose centralorifice is fitted with a female thread and receives a screw-plug 11. Astrainerdisk 12 is supported at the lower end of the tube. The tube 1 ismade very much larger than the paste-tubes c and is filled solid withpaste. i

When it is desired to fill the tube 0, it is unscrewed at the top fromthe head i, care being taken to push the plungerf to the lower end ofsaid tube, so that its under face is about flush with the lower end ofthe tube. The screw-plug 11 is then removed and the hand-wheel 8 turneduntil the solid core of paste appears at the mouth of the nozzle or cap10. The tube 0, with its lower end, containing the plunger, uppermost,is then screwed into the female thread of the nozzle 10. The plunger 4isthen forced down, thus squeezing the paste in a solid mass into the tube0 without the admixture of any air. \Vhen the paste has driven theplunger f nearly to the other end of the tube a, the operation isstopped and the tube is-removed and replaced in the machine.

The advantages secured by my invention involve the keeping of the pastein perfect condition, the avoidance of waste by not permitting the pasteto dry or sour, and the accurate regulation of the quantity applied, sothat neither too much nor too little will be used in each blank. It willbe noticed also that the mechanism is so arranged that it acts inprecisely the same Way on the blank whether the pile of blanks be largeor small. It also permits the application of the paste to exactly theright points of the blank what ever the size or shape of the collar orcuff blanks may be.

The rapidity with which the machine can be run is in practice limitedonly by the speed with which the operators can pick off the successiveblanks and paste them.

It will be observed also that the paste-applying devices need have but asimple reciprocating movement in a vertical plane and that there is nonecessity of employing mechanism for compounding a lateral movement withthe vertical movement. As the weight of the reciprocating parts can benearly counterbalanced, it is obvious that but very little power isrequired to run a machine.

It will be understood that the machine shown and described hereinillustrates only one embodiment of my invention and that changes can bemade in the form and arrangement of parts and that different mechanicalmovements from those actually described may be substituted to accomplishthe same results. I
